I think the trouble comes from the concept "a job" to begin with. It's a vestige. The historical trend that goes slavery -> serfdom -> indentured servitude -> wage slavery runs right up to the modern job. Looked at from this perspective, the rhetoric around "loyalty" and "security" sounds remarkably feudal.
This historical trend is continuing, the old forms are breaking down, and our little corner of society (the software startup world) is one edge of whatever is emerging to replace "jobs". It isn't clear yet what the next form is. But these angry arguments about who owes what to whom are symptoms of the churn of this process.
Personally I think it would be great if we eventually moved fully beyond the master-slave relationship. As someone with a strong aversion to both sides of that dichotomy I find it a little annoying to be part of a civilization based on it.
